China Minmetals network structure of tungsten carbide complete sets of technology to enhance the international competitiveness of China's tungsten carbide

Tungsten carbide is an important category in new materials, is "China made 2025" delineated advantages and one of the strategic industries, China Minmetals Corporation owned Zhuzhou Tungsten Carbide Group Co., Ltd. (hereinafter referred to as "strain hard group") in the country to take the lead Network structure of tungsten carbide research, through the joint technical research in Central South University, successfully developed a network structure of tungsten carbide complete sets of technology, the Office of Science and Technology of Hunan Province reached the international leading level, changed the past 20 years, China's overall strengthening of tungsten carbide products technology development Slow and unfavorable situation for the development of high-end tungsten carbide products and traditional tungsten carbide product quality improvement provides a new technical means.
The research and application of tungsten carbide are of great significance to support the construction of major national projects, to promote the transformation and upgrading of traditional industries and to build new advantages of international competition in China's manufacturing industry. At present, China's conventional tungsten carbide products difficult to achieve advanced excavation technology and service environment changes in the requirements, seriously restricting the major projects and related downstream industry development. Mesh tungsten carbide is the new direction of international tungsten carbide research, compared with the existing technology, in the wear and tear requirements, especially supporting heavy duty drilling equipment and drilling hard rock layer has obvious advantages. Over the years, the world's tungsten carbide countries have attached great importance to the technology research, but did not make a breakthrough.
The company is the strongest in China's tungsten carbide field, the highest market share of the company, with China's well-known trademark "Diamond" trademark and Tungsten Carbium State Key Laboratory, its research and development of the network structure of tungsten carbide technology to composite materials As a means to improve the wear resistance of materials through high hardness, high toughness matrix effectively resist the crack propagation to ensure the overall toughness of the material, thereby significantly improving the coordination of the key mechanical properties of tungsten carbide, especially suitable for rock drilling and other wear and tear, High efficiency, high efficiency, environment-friendly, structurally controllable, easy to large-scale industrialization, and the existing equipment and process fit high degree of characteristics.
The rapid development of the solid-scale structure of tungsten carbide plant, the first in the world to achieve a large-scale industrial production, the establishment of the world's first and only an annual output of 200 tons of mesh alloy production line, developed a Better toughness and wear resistance matching drilling new materials, products in Australia, Brazil and large domestic mines, oil field field test shows that its service life exceeds the level of foreign advanced products, especially in iron ore, quartzite and other high hardness , Dense rock, product life than foreign high-end products increased by more than 1 times.
At present, the plant hard structure of the tungsten carbide has completed the cumulative output of 850 tons, more than 90% of related technology products directly or assembled into a diamond into the international market, the output value reached 400 million yuan, driven by the relevant industry added value reached 2 billion yuan, thus Significantly improve China's tungsten carbide products and supporting the international competitiveness of drilling tools, greatly improving the international image of China's drilling rig.
